It's a track that doesn't contain a wavefile and is generally used for creating subgroups or submixes. Audio passes through it and isn't recorded as a file. For example, instead of sending the output of each drum track to your master fader, which represents your stereo outputs from the virtual mixer or your soundcard, you can send each drum to a stereo subgroup (auxilliary track) where you can turn up the volume of the entire drumset without having to turn up the volume on each individual track. You can also add compression, EQ and what ever else you can think of to the entire kit . Then you send the output of the "aux" to the master fader. I imagine you can create auxilliary tracks in CEP because you can in Adobe Audition which is essentially the same program.

I can't think of one DAW that DOESN'T utilize auxilliary tracks so my guess is everyone can. Actually, I just upgraded my Pro Tools sytem. The old one gave me 16 auxilliary tracks and the new one gives me 32. So that's 16 better right? Maybe PT can come out with a Nigel Tufnel version and have 33 auxes.

Jessen, it's no different than the mixing board you use when you play live. An auxilliary is just a subgroup. Each track in Cool Edit Pro probably has an input and an output. Most of the time the output goes to the master fader which sends the signal (sound) to your stereo soundcard. BUT you can send a track's output to other places including an "auxilliary" track. You do this by sending it on a "buss". You select the output of your track to, for example buss 1. Then you go to an "auxilliary" track (read your manual!!) and set the input to "buss 1". Then you send the output of the "aux" track to the master fader which is usually "Analog 1-2" If you don't do this you won't hear the "aux". Every program might use different language but it's all the same. Remember, every track has an input and an output and you can configure these any way you want (signal flow is like water) If you have already recorded something on a track though, you don't need to set an input, you just need to set up an output for that track. Either send it to your master fader or to a buss which will carry the signal to an auxilliary track. Then set the output of the aux to your master fader.The only way this is going to make sense to you is to DO IT!! You'll see how easy it is to do (and how hard it is to explain)

thanks eddy I will try it

I remember Cool Edit having an "Edit" view and a "Multitrack" view. In Adobe Audition, which is what Cool Edit became, you can go to "Multitrack" view and choose to see a "Mixer" instead of the "Main" tracks. Can you do this on Cool Edit?

Go to the bottom of the mixer track that you are using where it says "Master". Click on that and find something that says "Add Bus" or something like that. In Adobe Audition this automatically creates an aux track called "Bus A". You'll also find that the output of your mixer track will automatically be sent to "Bus A" and that the output of the "Bus A" track is being sent to the Master outputs.

FWIW, the term "Multichannel" usually refers to 5:1 surround sound.

Ok, I figured out how to create the busses, but I still can only pan left to right and not in surround - which is what I am trying to do. I want to have sound coming from all directions.

I'm not using speakers, just a set of headphones. I'm not sure what the sound card is but I know that it won't let me use the multichannel encoder. Maybe a new sound driver would work?
